Amazon debuted a more sophisticated version of Alexa on Wednesday that’s more conversational and can handle tasks on your behalf. But in a surprising departure from its usual playbook, the company didn’t announce new Echo devices to go with its revamped digital helper.

The new Alexa+ is getting good press so far, but it's not clear whether consumers will find it compelling enough.

Amazon.com. Inc will release companion devices in the fall for the artificially intelligent version of the Alexa voice assistant, Chief Executive Officer Andy Jassy said in an interview with Bloomberg Television.
